Aug. 211, w23. HAMAS@ w. sANDlFoRD FEED PINION Films. Jun@ s, 1921 five/i Z071' patented lang, 2l, 1223i ings, a sha einer tw t lptfihdd@ @ATNT FFHQEO' I hnplieonen tiled nneJ, 1221., [Berici 11o. 674,070. l
To all whom, 'it may concern:
Be it oivn that l, WM Sniiorrom, e citizen et the United States, residing at Joliet, in the county of Will and Stateot lllinois, have invented certain nevvanduseiul lim rovements in a lleed Pinion, et which t e following is a specication.
My invention relates to a feed pinion and has particular reference to a ieed pinion for planing machines and the like and `ivherein. motion is transmitted from a gear Wheel to a shaft in one direction. The device is ap plicable also to lathes and to various other machines vvhere motion is transmitted by means of rs, pinions or the like..
A further obJect of my invention 1s the provision oi a feed pinion or transmission mechanism which is positive in its operation in one direction and which does avvay entirely with the setting oi thunilo latches, dogs or pavvls, and furthermore, is simple and emcient in operation.
li. further object oi my invention is the provision et a feed pinion particularly o adapted for use in planer-s so that the planing tools can he fed in one direction and then reversed by slippin the driving pinion ed the drivin shaft an reversin it end to end so that t e motion is transmitted to a shaft in the op osite direction. rllhis provision has not heretofore been possible in devices ot this sort Without various adjustments.
'.lhese and other objects et my invention `ivill be more fully and better understood hy reference to the accompanying sheets oi' drawings, and in which- Figure 1 is an end elevational view oir' a pinion embodying my improved invention having a shaft inserted therethrough Figure 2 is a vertical sectional view on line 2-2 of Figure 1; c
Figure 3 is an end sectional vievv on line viin-3 of Figure 2; and
Figure 11 is a side View in elevation of a bushin upon which the pinion is mounted and W ich is secured to a shaft in any approved manner.
Referrin now specifically to the drawt 1() of a machine leading to the feeding mechanism is shown having a bushing 11 adapted to he inserted over the shaft 'and having a longitudinally extending keyway 12 therein into which a key 13 is fitted, the said key 1 3 extending into a key- Way 1d extending longitudinally ot the shatt 10, or a stud may he secured to the shaft 10 which extends into the keyvvay l2 in the bushing 11. The bushing 11 is mounted upon the shaft 10 and at one oi its ende l1 has a series oi recemes 15 extending circujmierentially around the bushing 11, the said recesses 15 having the ap earance et corrugations upon the wall of t e bushing 1l. A pinion 16 is provided into which the bushing 11 is tted, the bushing 11 also having a shoulder 1'? extending circumferentially therearound, and which abuts against a shoulder 18 in the pinion 16. The pinion 16 haa a series of teeth 19 thereon and at one of its ends is cut away and a collar 20 inserted under the teeth 19 and which surrounds the end 11G of the bushing 11. A. second collar 21 is rovided which ts `over the end 22 or" the bushing l1 and against a shoulder 23 extending circumt'erentially around the end ot the hushing adjacent the recesses 15 and against which the collar 21 abats., The collar 21 is held in position hy screws 24., '25 and 26 which pass through the collar 21, also the collar 20 and into the gear vvheel 16 so that the gear Wheel 16 and the tvvo collars 2O and 21 respectively, and the bushing 11 are securely held together as a unit so that the pinion 16 can he slipped ed the shaft 10 and turned around end to end and the motion ot the pinion reversed so that the shaft 10 can be turned in either direction, as hereinafter described. ln the collar 20 is a series of recesses 27, 28 and 29 extending entirely through the collar 20, into `Which balls 30 are inserted and which grip the bushin 11 by dropping into the recesses 15 in t e bushing 11 and coming into contact `with the bottom and sides oi the recesses 15. lhe balls 30 are retained in the recesses 27, 28 and 29 by the end of the pinion 16 and the collar 21. rlhe recesses 27, 28 and 29 in the collar 20 are deeper at one side than at the other, and therefore extend dia onally in the collar 20 so that the balls 30 hy being in the deepest part of the recesses are entirely out of engagement with the bushing 11 as the pinion 16 is turned upon the bushing 11. As illustrated in Figure 3, as the pinion 16 is turned to the left the balls 30 will be forced into the rear or deepest portion oit' the recesses, as shown in the drawing, but immediately the direction of the pinion 16 is reversed the balls 30 -will he forced into the recesses 15 in the Sil sleeve 11. by the wall of the collar 2O and by gravity, so that the bushing 11 is gripped by the collar 2O and motion transmitted to the shaft through the key 13.
It 'will also be understood that rollers may be substituted in the place of the balls 30 and the same result accomplished.
While ll have described more or less pre cisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion. ot parts and the substitution ci equivalents as circumstances may suggest or render expedient Without departing Jrom the spirit or scope of my invention.
l ciaim:
l. A reversible feed pinion comprising in combination a bushing having a series of longitudinally extending corrugations at' one of its ends, means adapted to detachably secure the said bushing upon a shaft, a pinion rotatably mounted upon said bushing, a collar secured to said pinion having diagonally extending recesses therein and a plurality of movably mounted balls in said recesses adapted to engage the said bushing Whlen the pinion is rotated in one direction on y.
2. A reversible feed pinion comprising in combination a bushing having a series of longitudinally extending corrugations at one of its ends, means adapted to detachably secure the said bushing upon a shaft, a pinion rotatably mounted upon said bushing, a collar secured to said pinion having diagonally extending recesses therein, and a plurality of movably mounted balls in said recesses adapted to engage the said bushing When the pinion is rotated .in one direction only, the bottom oit' the said corrugations corresponding in contour to the curvature of the said balls.
